so pathetic me, is charging with four of these CEN-TECH $5.00 dollar chargers from Harbor Freight, they put out 750 miliamps
this is one of the things that I have learned works, that is if you don't have a 48 volt battery charger you can use four 12 volt battery chargers or two 24 volt battery chargers to charge your 48 volt battery pack, yes there are some stipulations but I'll let the experts tackle that
so how long does it take? a very long time, so long I time my charge with a calendar, lol, that's right I think it takes about 4 days to charge my pack from 48 volts to 51 volts and some change, (again the experts can chime in how we should not completely deplete our packs, but I am still trying to figure things out so I am not even sure if 48 volts is good or bad)
things that suck are that I can't even plug in all four of these ac adaptered chargers into a single seven port power surge protector strip thingie, because the one closest to the on/off button interferes with it and turns the darn thing off so I have to start in the next one over - see these are just all the little things they don't teach you in school - jk
